Enter the mass of the planet and the radius of that planet into the calculator below to determine the escape velocity.

## Escape Velocity Formula

The following equation is used to calculate the escape velocity from any planet or large object.

ev = (2* M * G / R)^0.5

- Where ev is the escape velocity (m/s)
- M is the mass of the planet (Earth = 5.972 × 10^24 kg)
- G is the gravitational constant (6.674 * 10^(-11) N * m^2 / kg^2)
- R is the radius of the planet (m) (Earth = 6.371 million)

In the case of earth, the escape velocity will depend on the values for mass and radius presented above. The escape velocity is solely dependent on these two values. It’s important to note that this velocity is the speed needed to leave the planet, not to orbit. That value is called the first cosmic velocity. While the escape velocity is considered the escape velocity.

## Escape Velocity Definition

An escape velocity is the velocity that an object needs to travel to escape the gravitational pull of a larger body.
